LONDON — Former “Game of Thrones” co-stars Kit Harington and Rose Leslie married Saturday with a church service and a celebration at the bride’s ancestral castle in Scotland.

The couple and guests arrived for the afternoon service at Rayne Church, close to the 900-year-old Wardhill Castle in northeast Scotland, which is owned by Leslie’s family. Harington, wearing a morning suit, and Leslie, in a flowing ivory gown and veil, smiled at members of the public who had gathered outside the church.

Later the newlyweds were showered with rose petal confetti as they left the church and drove off in a Land Rover festooned with “Just Married” signs to a reception on the castle grounds.

Harington and Leslie, who are both 31, met in 2012 on the set of the HBO fantasy series, where they played a couple as the characters Jon Snow and Ygritte. Leslie left the cast in 2014 and currently stars in US legal drama “The Good Fight.”
